kconfig: fix silentoldconfig

2008-09-29T15:03:01+00:00

Recent changes to oldconfig have mixed up the silentoldconfig handling, so this fixes that by clearly separating that special mode, e.g. KCONFIG_NOSILENTUPDATE is only relevant here, the .config is written as needed. This will also properly close Bug 11230. Signed-off-by: Roman Zippel Signed-off-by: Linus Torvalds

kconfig: always write out .config

2008-08-04T20:18:07+00:00

Always write out .config also in the case where config did not change. This fixes: http://bugzilla.kernel.org/show_bug.cgi?id=11230 Signed-off-by: Sam Ravnborg Cc: Josh Boyer Cc: Adrian Bunk

kconfig: make defconfig is no longer chatty

2008-07-25T20:12:51+00:00

make defconfig generated a lot of output then noone actually read. Use conf_set_all_new_symbols() to generate the default configuration and avoid the chatty output. A typical run now looks like this: $ make defconfig *** Default configuration is based on 'i386_defconfig' arch/x86/configs/i386_defconfig:13:warning: trying to assign nonexistent symbol SEMAPHORE_SLEEPERS arch/x86/configs/i386_defconfig:176:warning: trying to assign nonexistent symbol PREEMPT_BKL ... arch/x86/configs/i386_defconfig:1386:warning: trying to assign nonexistent symbol INSTRUMENTATION $ As an added benefit we now clearly see the warnings generated in the start of the process.

kconfig: make oldconfig is now less chatty

2008-07-25T20:12:50+00:00

Previously when running "make oldconfig" we saw all the propmt lines from kconfig and noone actully read this. With this patch the user will only see output if there is new symbols. This will be seen as "make oldconfig" runs which does not generate any output. A typical run now looks like this: $ make oldconfig scripts/kconfig/conf -o arch/x86/Kconfig $ If a new symbol is found then we restart the config process like this: $ make oldconfig scripts/kconfig/conf -o arch/x86/Kconfig * * Restart config... * * * General setup * Prompt for development and/or incomplete code/drivers (EXPERIMENTAL) [Y/n/?] y Local version - append to kernel release (LOCALVERSION) [] ... The bahaviour is similar to what we know when running the implicit oldconfig target "make silentoldconfig". "make silentoldconfig" are run as part of the kernel build process if the configuration has changed. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: speed up all*config + randconfig

2008-07-25T20:12:49+00:00

Drop the chatty mode when we generate the all*config, randconfig configurations. Ths speeds up the process considerably and noone looked at the output anyway. This patch uses the conf_set_all_new_symbols() function just added to kconfig. Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: tristate choices with mixed tristate and boolean values

2008-01-28T22:21:18+00:00

Change kconfig behavior so that mixing bool and tristate config settings in a choice is possible and has the desired effect of offering just the tristate options individually if the choice gets set to M, and a normal boolean selection if the choice gets set to Y. Also fix scripts/kconfig/conf's handling of children of choice values - there may be more than one immediate child, and all of them need to be processed.

kconfig: use C89 random functions in conf.c

2008-01-28T22:14:38+00:00

rand and srand functions conform also to C89 in addition to POSIX.1-2001, which makes them a bit more portable (work also on MinGW host). Linux man page also says: "The versions of rand() and srand() in the Linux C Library use the same random number generator as random() and srandom()". * Use C89 conformant functions rand() and srand() Signed-off-by: Ladislav Michl Signed-off-by: Sam Ravnborg Cc: Roman Zippel

kconfig: use getopt() in conf.c for handling command line arguments

2008-01-28T22:14:36+00:00

Switch from doing our own parsing of command line arguments to using getopt(3) to do it. Aside from simplifying things, this allows us to specify multiple arguments; the old code could only accept two arguments (input_mode and kconfig name). Note some subtle changes: - The argument '-?' is no longer supported. - '-h' is not treated as an error, so output goes to stdout, and we exit with '0'. - There is no compatibility checking amongst arguments; the last option will simply override earlier options. For example, 'conf -n -y foo' is perfectly valid now (input_mode will be set_yes). Previously, that would have been an error ("can't find file -y").
